ABSTRACT:
The invention relates to a circuit arrangement for operating a discharge lamp, comprising a DC-AC converter provided with switching elements and a drive circuit for rendering the switching elements alternately conducting. The circuit arrangement is furthermore provided with a control circuit C for controlling the power consumed by the lamp. To this end, the control circuit is coupled to a current sensor. According to the invention, the current sensor is so positioned that the power consumed by the lamp can be controlled independently of the build-up of the drive circuit and that a simple construction of the control circuit C is possible.
